摘要:
AbstractSugars were separated gas chromatographically on short apolar glass capillary columns by using cold, on‐column injection (OCI) techniques. After silylation, oligomers up to the hexasaccharides could be efficiently separated in resonable retention times. Response factors of silylated sugars were determined as a function of varying sample amounts and concentrations. The optimum injection amount was found to be 1 μl in heptane as solve

摘要:
AbstractTetraiodo‐L‐thyronine (T4) in human serum was determined by HPLC using a nonphysiological internal standard. For sample preparation, a cation exchange resin, RP‐chromatography on C‐18 or phenylphase, and electrochemical detection (Metrohm 656 or BAS‐LC 4 A) were employed. The mobile phase (0.8 ml/min) was 10 mMH3PO4/CH3OH (40/60 v/v) or 10 mMH3PO4/CH3CN (70/30 v/v, 1.5 ml/min), the voltage applied 800 mV. The coefficient of variation (day to day) was 6.8% (N = 40); concentrations of T4 found were 11 to 20% lower than those obtained by two different commercially available imm

摘要:
AbstractTwo commercial preparative liquid chromatographs have been evaluated for gram‐scale purification of steroid esters. The Jobin‐Yvon and Waters chromatographs both allow fast separations. Neither system has a high intrinsic column efficiency, but the resolving power of the Waters system can be increased by the use of recycle. A laboratory‐assembled preparative liquid chromatograph is described which is economical both in construction and operation, versatile, and considerably more efficient than the two commercial alternatives for single runs on up to a gram
